A200 watt t. v. is used for 20 hours in a week. if it is used for four weeks then what is cost of electricity if rate is 5rs/kwh

80rs

Explanation:

you can calculate

t_total  = 20h/week * 4 weeks = 80 hours

200w = 0,2kw

cost = 5rs/kwh * 0,2kw * 80h =  80rs

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
